[0026] Such as figure 1 As shown, the embodiment of the present invention provides an image processing method applied to a mobile terminal, where the mobile terminal includes a first camera and a second camera, and the image processing method specifically includes:

[0027] Step 101: Obtain a first image captured by the first camera and N frames of images captured by the second camera within the same time period.

[0028] Among them, the first image is a normal exposure image, and the N frames of images are all underexposed images. The start time of image acquisition by the first camera and the second camera is the same, and the first exposure time of the first camera is the second exposure of the second camera. N times the duration, where N is a positive integer. Further, the duration of the shooting time period is the first exposure duration of the first camera. That is, one frame of the first image captured by the first camera within the first exposure time period and N f...

Abstract

The invention discloses an image processing method and a mobile terminal. The method comprises: obtaining a first image collected by a first camera and N frames of images collected by a second camera within the same time period; Composite processing to generate the final output target image; wherein, the first image is a normal exposure image, the N frames of images are all underexposed images, the start time of the first camera and the second camera to collect images are the same, and the first camera's first One exposure duration is N times the second exposure duration of the second camera, where N is a positive integer. The image processing method of the present invention realizes electronic anti-shake by adopting dual cameras, and synthesizes 1+N frames of image data to obtain an output image with rich details and high image quality, thereby realizing electronic anti-shake; in addition, the image processing The method is applicable to multiple application scenarios such as single shooting, continuous shooting, panoramic photography and video recording, and solves the problem of large limitations of electronic image stabilization.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an image processing method and a mobile terminal. Background technique [0002] With the development of communication technology, mobile terminals have more and more entertainment functions, among which, the camera function, as one of the core entertainment functions, has become an important aspect for users to consider mobile terminals. In the prior art, single-camera technology is usually used to achieve photographic imaging, but due to the limitation of the performance of the single-camera photosensitive chip, the obtained photos are prone to loss of details, and imaging problems such as picture shaking and smearing are prone to occur during the shooting process. In order to solve imaging problems such as image shaking and smearing during shooting, hardware components are usually added to achieve optical image stabilization, but due to the high cost, it can only...
